Do someone know how to access the database used by the Opera PMS software ? Is there a general answer for all Oracle database... the only info i found was about this command
sqlplus hr/my_hr_password#host_computer_name
is SQL plus installed with all Oracle software ? My goal is to make batch file, find some data in the Remote Database that had just been created by Opera PMS, save them on my local drive to a text file for the next step... Any clue will be very helpfull ... i 'm total noob in DB and dont want to mess up the system (i'm lazy employee but want to keep that one :-)) Blessed love
If Oracle wanted developers to have programmatic access to the Opera data then they would provide an API for that. They don't. Opera PMS does an export function, OPP_EXP Export Files, but apparently it's a chargeable extra. How very Oracle:)
Basically if your company pays for OPP_EXP Export Files you should use that. If they don't then attempting to get data out of the database by your own means would probably jeopardise your company's license agreement (although I agree it would be unlikely that Oracle would ever find out).

I have downloaded the SQL Developer. Currently, I am using my school database but it is for temporary use. I want to use it after finishing my college. I do not know how can I make local connection in SQL Developer. Can you please help me in this.
Oracle SQL Developer is a tool you use to access an Oracle database.
So, if you want to use Oracle on your own computer, regardless there is (or is not) a connection to your school network, you'll have to install the database as well. I'd suggest Oracle 11g Express Edition. The installation process is simple; more or less, clicking NEXT a few times does the job. I'd, though, recommend you to follow the Installation Guide and pay attention to what the Installer asks (for example, write down passwords you choose).
Furthermore, in order to "copy" the database (actually, I believe you mean "schema" in this case) to your database, the right way to do that is to use Data Pump. You'd use Export in school to export the database, and Import on your computer to import it.
However, as Data Pump requires access to a directory (it is an Oracle object which points to a file system directory, usually on the database server; it is created by SYS and other users are granted read and/or write privileges on it). If you can't get access to it, you can use the original EXP and IMP utilities. EXP creates the DMP file locally; you'd put it onto a memory stick (or, if you're on the network, copy it directly to your PC) and import it.
If you're unsure of whether you can (or can not) do that, ask your teacher.
Once the schema is imported into your database, use SQL Developer to access it. Should be no problem to do that.
I have been tasked with creating some backups for some Oracle Apex apps (Application Express v4.1.1.00.23). The request is to back up both the applications & referenced db objects (not sure if this means just structure or structure & data).
On the one hand, I would have expected standard db backups to handle most or all of this but I'm very new to Apex so it's all a learning curve.
I'm currently exporting the application from apex and then exporting (using SQL Developer) all the database object dependencies that Apex gives me - although I see that the list doesn't include functions that are used for auth.
This seems a really clunky process that's very prone to mistakes (miss an object, save something to the wrong place, no guarantees of consistency etc).
Does Apex (my version!) offer something to do the job or is there something else I could be doing? I've had a good google but nothing has stood out.
UPDATE: I realise now that I should have included some extra info. I'm currently at a large organisation & I believe our db backups (which I guess/hope are done using rman) are done by a different department. I think the motivation for the request is so that we have some local, easily accessible backup so that if one of the developers messes something up we don't have to go through multiple layers of organisation (& undoubtedly a lot of time) to sort ourselves out. I suspect that some kind of source control would be a great starting point but I'm not sure how far I'll get with that idea - especially as we seem to have little in the way of autonomy over things like servers.
RMAN is the way to go to backup an oracle database:
https://docs.oracle.com/database/121/BRADV/toc.htm
there are tons of material on the hows and whys online; just google "oracle rman" and you'll find what you need (the documentation should cover you as well of course).
cheers
Standard DB backups will include everything you need.
The Apex applications I develop are static, meaning the end users make no changes to the Apex application, and there is no need to make a specific backup other than to store the original apex application .sql installation files in a safe place.
If you must, you can make an export of the database schemas the application uses. For example with the expdp utility.
IN apex you need to take 2 backups one in the workspace
Second your application
Third is while using export import from the database it tends to loose & character in procedure ..So beter use rman and take a complete backup.
I have found this Oracle white paper Life Cycle Management with Oracle Application Express (Revision 2) which does what it says on the tin - including various strategies for exporting, backing up & managing 'lost application development'. It's a really good read and I'll be using it as a template for suggestions of how we can manage our process in future.
I need to automate a selective table / user object backup I currently am doing via PL / SQL Developer.
The way I currently do it is via Tools/Export Tables and Tools/Export User Objects, manually select tables / objects, then set the options, choose destination and export. I do this from a windows laptop and the database is located in a suse linux server, both are in the same LAN. DB is running 24/7 and can not be shutdown. Also currently my oracle programming skills are very basic as I only do maintenance to this solution. I would like to keep doing the backup process in the windows laptop, but I would consider a server side script solution also and then retrieving the .sql files from server.
Thanks in advance
I wouldn't really call it a backup, but look at exp/imp and expdp/impdp (data pump) in the Utilities manual
As Gary implies exp/imp really isn't a backup solution. If this database is important to you or others, figure out how to use RMAN , which is usually configured to run in a mode that doesn't require the database to be shut down. Although it executes on the database host and for non-tape destinations must write its files to a filesystem attached to the host, it can be launched remotely.
RMAN is aimed at restoring/recovering the entire database, so if what you're looking for is only the ability to recover isolated objects it may not be for you.
So I'm coming from a position as a SQL Server developer who has written a little bit of PL/SQL way back in the mists of time but effectively knows nothing.
I've got a laptop, it's running Oracle. There is a database on the laptop which I need to have a look at and neither I, nor anyone else I can speak to, knows what it's called.
I have a couple of logins including one which alleges to be an Admin login.
What's the easiest way to browse the databases on the server and then connect to one?
I suspect that my assumptions about relationships between servers, users and databases from SQL Server are leading me astray but right now I can't get past idea that the client tools Oracle ships are someone's idea of a joke but I'm really not finding it that funny.
I'm pretty sure that it's version 9.2 that's running.
Happy to provide more information but right now I don't know where to start.
If this is windows look in the services. Each database will have a separate service. By default these are named OracleServiceDATABASENAME.
You may be able to connect with just this information on the default port 1521.
If that does not work open the properties of that service you can find the location of the oracle home. The default place to keep your connection information in the ORACLEHOME\network\admin\tnsnames.ora . Using the database name you can find your connect information in this file.
If this is linux/unix look in the /etc/oratab file. This should have the database name and oracle home listed. The default location of the tnsnames.ora file is the same as on windows.
Once you have this information you can use any of the tools mentioned above to connect to the database.
I don't know what qualifies as "easiest" in your book. I'm moderately fond of Aqua Data Studio (www.aquafold.com); it's nice & visual & pretty & all. It's also Not Cheap, but might be worth a 2-week evaluation to see if it does anything helpful for you. I'm not an expert on this, and I joined an Oracle-based group from a SQL Server background; that's the tool they were using at the time, and I've found it extremely usable. But that's just me. Good luck.
Check out Oracle SQL Developer. (It's free)
I'm not a SQL Server expert, but there are differences in terminology.
An Oracle "Instance" is a single entity of the Oracle software. A database is the actual logical data that the instance serves. You may have multiple instances of the Oracle database software running against one database (This is considered a RAC setup); or just one instance running against one database.
I'm assuming what you mean by database here is actually the different schemas/users/tablespaces/procedures etc. that you have within an Oracle database. In that case, Oracle SQL Developer should do the job nicely.
If you are able to utilize Enterprise Manager (this is a licensed option), it provides this functionality as well, though it is more cumbersome than SQL Developer IMHO. EM does provide many other tools for providing a general overview of your Oracle instance health, alerts, and many things used to help tune the performance of your Oracle instance.
In Windows, the following command lists running database services:
net start | findstr -i ora
In Unix/Linux, grepping for the Oracle SMON process will give you the names of running databases:
ps -ef | grep smon
I have an Access application with a SQL server back-end, mixed with quite a few DB objects local to the Access app. I've tried running SQL Profiler, but I got very little except a cryptic sp_execute 2,4288,4289,4290,4291,4292,4293,4294,4295,4296,4297.
I would like a trace tool that is local to the Access DB, so I also pick up any activity that doesn't go back to the SQL server.
As far as I know there is no such facility within Access but, depending on your case, you could try these few things:
Write a wrapper against SQL executables: that would mean replacing all calls to Execute, OpenRecordset etc within your VBA to an alternative version that would log the query.
This isn't going to catch everything obviously but it could help.
Move your local tables to another database and use ODBC to relink them to your original Access application. You can then use ODBC's logging facilities.
This could be the best altenative as it's fairly easy to setup for debugging.
It's not the best solution for a production environment though as all your calls to local tables will in fact go through ODBC, but again, it's a temporary solution for debugging.
Use ShowPlan and ISAMStats to view how Jet/ACE interprets your queries and get other database activity stats.
It's easy to setup by writing a key to the registry and you'll end-up with a log describing how your queries are analysed.
It's more useful for optimisation than logging but again, it could help.
Use Flextracer, a shareware, free for 30 days or so. My colleague here has just found this for us as we were going through a similar situation. Problem solved.
